To all whom t may concern.'

Be it known that I, HENRY IzAnn, a citizen of the United States, residing at Port` land, in the county of Multnomah and State of Oregon, have invented certain new and useful Improvements in Liquid-Fuel Burners; and I do declare the followingto'be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to liquid fuel burners, and more especially to such as have al perforated burner tube; and the object of the same is to produce a device of this character capable of being placed within the lirebox of an ordinary stove or range and supported therein on two standards rising from the grat-e.

This and other objects are accomplished by the construction hereinafter more fully described and claimed, and as shown in the drawings whereine Figure 1 is a side elevation of this improved burner, showing it disposed within a stove which latteris illustrated in section; Fig. 2 is an enlarged plan view of the burner complete. Fig. 3 1s an end elevation of the burner shown in Fig. 2. Fig. 4 is a central longitudinal section on the line 4-4 of Fig. 2. Fig. 5 is a horizontal section on the line 5-5 of Fig. 4. Fig. 6 is a. cross section on the line 6 6 of Fig. 2; and, Fig. 7 is a perspective det-ail to be referred to hereinafter.

In the drawings let the letter S designate an ordinary stove mounted on legs L and having a grate G above its ash pit A and beneath its fire box F. The object of the present invention is to place a burner within the fire box instead of heating the same by solid fuel, and to connect the burner with a source of liquid fuel supply-perhaps an elevated tank containing liquid fuel such as gasolene, kerosene, or any proper distillate.

In the drawings the numeral l designates a feed pipe which is led, through asu'itable controlling valve 2, to and through the side of the stove at the point 3, to and through an expanding extension V4, Vand into onetendV of what might be called a heating tube 5 which is of larger diameter than the feed pipe 1. At its other or outer extremity this tube 5 is connected through an elbow 6 with a cross pipe 7 and the latter through a second elbow 8 with a second heating' tube 9 parallel with and constructed like `the first but spaced some little distance therefrom; and each of said elbows has a reducing extension 15 in line with the axis of its tube. yThe opposite or inner end of the second tube 9 is connected, through a peculiar form of coupling best seen in Fig. 7 with a burner tube yet to be described. This coupling comprises a tubular body 11 having internal threads 12 at its outer end to engage the extremity of the tube 9, a compound elbow 13 rising from said body with its outer end directed along a line parallel with the line of said body but reduced and internally threaded as at 14, and a reducing extension 15 at the inner end of said body, having a nipple 16 projecting therefrom as best seen in Fig. 7. Screwed into the threaded end 14 of the compound elbow 13 is a burner tube 17,.herein shown as somewhat smaller than the heating tubes 5 and 9 but larger than the feed pipe 1, and the outer end of this tube is closed by a cap 18 while its lower side is pierced with a number of jet openings 19, whereof only two are shown in Fig.4., v

rIhe support for this device is extremely simple. It consists of two like standards 20, each having a base 21 which may rest upon the grate G or be secured thereto, and a T- coupling 22 at its upper end, and into the head of the T are passed or secured the inner ends of two short sections 23 of rods. At the inner end of the burner the outer extremity of one of these rod-sections carries a T-coupling 24 through which the feed-pipe l passes freely and uninterruptedly, whereas the other rod-section carries a T-coupling 25 whose head has one end'connected by a proper nipple with the reducing extension 15, and its other end closed by a plug 26. At the outer end of the burner each rod-section v23 carries at itsouter end a T-coupling 27 whose head has its inner end connected by a short nipple 28 (see dotted lines in Fig. 2) with the reduced outer end of one of the elbows above described, and its outer end closed by a plug 29. It follows from this construction that the two standards 20 support the four rod-sections 23, and the latter at their outer extremities support both ends of the two heating tubes and they inner end of the feed pipe 1, while the heatingtube 9 through its Y. special form of coupling sup- `ports'the tube,l7 which stands above the reach all parts of the interior of the firebox level of both heating tubes and above a line drawn about midway between them.

A plate 30 is disposed in a plane Aabove said heating tubes and below the burner tube, its bodybeing provided with large holes 31 standing respectively beneath the jet openings 19, and with aseries of small perforations 32;

over and are bent downoutside of the two heating tubes 5 and 9 as best seen in Fig. (i. These fingers preferably stand inside the corner elbows or couplings, and by them the plate is supported in such manner that it may be removed for cleansing. Below the burner proper stands a pan 34, preferably `having a single fork 35 at each extremity (see Fig. 5), and each standard carries a collar 36 rendered adjustable by means of a set screw 37, with which collar said fork engages. Thereby is produced an adjustable pan for catching the diippings and for start-ing the burner by the customary method of permitting a little free oil to drop therein and igniting it with a match.

y All parts are of course of metal, and exact details are unimportant.

The uses of a burner of this type are so well known that they hardly need repetition here. The liquid flowing in through the feed pipe 1 passes through the heating tube 5 and then through theheating tube 9 and up the fixture shown in Fig., 7` into and throughout the length of the tube 17; mean` while it has been heated within said tubes 5 and 9 by the burning gases which are jetted downward from the openings 19 through the holes 31 in the plate 30 and onto the pan, and by the latter deflected so that the heat rises around both sides of both of the heating tubes 5 and 9 and converts the liquid fuel therein into vapor before it rises through the elbow 13 into the burner tube. lVhile I have shown but two jet openings 19 in the latter, it is obvious that there could .be a greater or perhaps a lesser number.

The purpose of the perforations 32 in the plate 30 is to permit the heat which is flashed downward through the holes 31 onto the pan 34- to rise freely so that it may F, although a large portion of said heat rises past the edges of the plate 30 and comes into direct contact with the heating tubes 5 and 9. The obvious purpose of the plugs 26 and 29 and of the nipples connecting the T- couplings with the inner ends of the second heating tube 9 and both ends of the elbows atthe outerextremities of the heating tubes,

is in order that when such plugs are removed a suitable tool will be passed through the tubes for cleaning them out. If the accumulations become too large to be handled in this manner it is quite possible to remove the T-couplings from the nipples, and withand from the four corners of this plate project fingers 33 which extend draw the latter .from the reducing extensions 15 at the outer ends of the elbows 6 and 8 or the special forin of coupling shown in Fig; 7 and thereafter a considerably larger 'tool may be inserted into and through these couplings and considerably larger-pieces of scale or other accumulations removed therefrom as will be clear.

That is claimed as new is: v Y -A e -1. A liquid fuel burner comprising a paii1 of spaced heating tubes connected at one extremity, a feed pipe connected with the inner end of one of said tubes, and a burner l, Y
